vertical center my navigation menu

Hey! I would really appraise if you could help me with my navigation bar. I bought a plugin called "max mega menu" , because I want stylish mega menus. But I can't center my navigation menu. I want it to be vertically in line with my logo.

Here is my subsite that I want help with: https://store.marbergs.se

I have also grant you access!

Greetings, Marcus
